LOS ANGELES, Calif. (FOX 11) - Authorities on Thursday chased a man in a pickup truck to a residence in the Glassell Park area before determining that no crime had occurred.

The pursuit began about 8 a.m. on the westbound Foothill (210) Freeway near Sunflower Avenue in the Glendora area, according to the California Highway Patrol.

Officers were attempting to contact the man after they were contacted regarding "a possible medical emergency,'' a CHP officer said, and followed the truck onto the southbound Glendale (2) Freeway.

The driver exited on Verdugo Road and at one point stopped on a surface street and started to get out of the truck, but confronted by officers with drawn weapons, drove off.

The man drove to the area of Weldon Avenue and Drew Street -- followed by a motorist in a truck that the man apparently had nudged aside with his pickup truck on a surface street while trying to elude officers. The man then got out of his pickup truck and went inside the residence.

Los Angeles police officers went to the location, and several people came outside about 9 a.m., but the man remained in the house.

After about an hour, police determined that the man -- whose name was withheld -- had an undisclosed medical problem.

"We were there to determine whether he was a danger to himself or others,'' said LAPD Officer Liliana Preciado. "We determined that no crime had occurred.''
